                         PROSPECTUS SUPPLEMENT SUMMARY

     This summary highlights information from this prospectus supplement, but
does not contain all the information you need to consider in making your
investment decision. To understand all of the terms of this offering and for a
more complete understanding of our business, you should carefully read this
prospectus supplement, the accompanying prospectus and the documents
incorporated by reference, particularly the section entitled "Risk Factors."
When we use the terms "Callon," "we," "us" or "our," we are referring to Callon
Petroleum Company together with its consolidated subsidiaries, unless the
context otherwise requires. If you are not familiar with the terms used to
describe the quantities, present value and other information about oil and gas
reserves, please see "Glossary of Oil and Gas Terms."

     We have been engaged in the exploration, development, acquisition and
production of oil and gas properties in the Gulf Coast region since 1950. Over
the past 11 years, we have grown our reserves and production by focusing on low
to moderate risk exploration and acquisition opportunities in the Gulf of Mexico
shelf area. We have working interests in 43 producing wells in the shelf area
and continue to generate growth in this area through the development of proved
reserves and exploration of prospects. In 1996, we announced our intention to
expand our areas of exploration to include the deep water area of the Gulf of
Mexico. In order to reduce the costs associated with exploring this productive
area, we drill wells with experienced working interest owners, including Shell
Deep Water Development, BP Amoco and Murphy Exploration and Production. In 1998,
we announced our first deep water discovery on our Boomslang prospect and
subsequently drilled three additional deep water discoveries at our Medusa,
Habanero and Entrada prospects. These four discoveries provided us with
significant additional net proved reserves. Our Medusa discovery is scheduled to
commence production in the fourth quarter of 2002 through facilities which are
contracted for and currently under construction. For the twelve months ended
March 31, 2001, we generated revenues of $68.8 million.

     As a result of our extensive operational, geophysical and technical
expertise in the Gulf Coast region, we have achieved substantial growth over the
past five years. From January 1, 1996 to December 31, 2000, our estimated net
proved reserves have increased 472% from 58.3 Bcfe to 333.7 Bcfe. During this
period, we generated a net drilling success rate of 69% and an average net
reserve replacement cost of $0.82 per Mcfe. As of December 31, 2000, our net
proved reserves had a pre-tax present value of $939.3 million and are comprised
of 60% oil and 40% natural gas. For the year ended December 31, 2000,
approximately 91% of our production was natural gas. Additionally, from 1996 to
2000, we have increased our annual production by 56% from 9.8 Bcfe to 15.3 Bcfe
and our revenues by 118% from $26.7 million to $58.1 million.

COMPETITIVE STRENGTHS

     Geographic and Operating Focus.  Our properties are located in the Gulf
Coast region where we have operated for over 50 years. During this time, we have
gained substantial experience in exploration, development and production of oil
and gas properties in this area. In 1989, we purchased our first property in the
shelf area of the Gulf of Mexico. Over the past 11 years, we have gained
substantial operating knowledge in the shelf area while achieving sustained
increases in production and net proved reserves. As of December 31, 2000, we
owned an 87% weighted average working interest in 43 producing wells. In 1996,
we purchased our first property in the deep water area of the Gulf of Mexico.
Our exploration experience in the shelf area as well as the experience of the
other working interest owners with whom we drill wells in the deep water area
has allowed us to successfully drill four deep water discoveries representing
251.9 Bcfe of estimated net proved reserves, as of December 31, 2000. In the
future, we will continue to focus on growth through the exploration and
development of both shelf and deep water properties in the Gulf of Mexico.

     Deep Water Development.  We have four significant deep water discoveries,
which are expected to materially increase our production beginning in 2002. In
March 2001, we signed a contract with J. Ray McDermott, Inc. to provide a
floating production facility at our Medusa deep water discovery. Development of
the production facility has begun and the facility is expected to be completed
and

                                       S-3
   4

producing in late 2002. After an initial startup period, we anticipate that the
facility will produce at its full capacity of 40.0 MBbls and 110.0 MMcf per day,
which is 52.2 MMcfe per day net to our interest. Approximately $48 million of
the proceeds of this offering and the senior note offering will be used to
complete this discovery. In addition, we intend to use a significant portion of
the proceeds of this offering and the senior note offering to develop our three
remaining deep water discoveries. Our Boomslang and Habanero discoveries are
expected to begin producing in 2003 and our Entrada discovery is expected to
begin producing in 2005.

     Extensive Shelf and Deep Water Exploration Potential.  We currently own
200,000 net acres in 92 federal blocks and 15,000 net acres in various state
leases and have an inventory of 21 shelf and 20 deep water exploration
prospects. We intend to drill 18 of the shelf prospects and two of the deep
water prospects in 2001, and intend to drill ten deep water exploration
prospects in 2002. We believe our exploration prospects and development of our
recent discoveries in the deep water area provide us with significant potential
for growth in reserves, production and cash flow in the future.

     Strategic Relationships with Leading Operators.  We have formed strategic
relationships with experienced deep water industry participants, including Shell
Deep Water Development, BP Amoco and Murphy Exploration and Production, to
explore the deep water area of the Gulf of Mexico. We believe these
relationships allow us to significantly reduce the risks associated with the
high costs of drilling wells in the deep water area while benefiting from the
significant upside associated with deep water drilling and remaining an integral
part of the decision making process.

     Technological Expertise.  We utilize the latest in 3-D seismic technology
to explore for oil and gas deposits in the Gulf of Mexico. As of December 31,
2000, we owned more than 950 square miles of 3-D seismic data in this area. We
believe this data allows us to lower the risks and costs associated with
exploration and development of oil and gas properties by increasing our
probability of success and allowing for better well placement when drilling. In
addition, in February 2001 we acquired a 50% interest in a partnership that has
access to 700 blocks of 3-D seismic data, representing 5,500 square miles, in
the shelf area of the Gulf of Mexico. We believe this partnership will provide
us with a significant opportunity to generate new prospects in the shelf area.

     Experienced and Committed Management Team.  Our senior management team has
an average of 28 years of experience in the oil and gas industry and an average
of 21 years of experience with us. Our President and Chief Executive Officer,
Fred Callon, has held his position since 1997. Prior to 1997, Mr. Callon had
held the position of President and Chief Operating Officer since 1984.
Additionally, our technical staff, which includes 14 engineering and geoscience
professionals, has an average of 21 years of experience in the oil and gas
industry and an average of eight years of experience with us. As of March 31,
2001, our directors, executive officers, and related parties owned 28.7% of our
common stock, which will decrease to 22.0% as a result of this offering.

BUSINESS STRATEGY

     The key elements of our strategy are as follows:

     Balanced Exploration Program.  We balance our exploration activities by
focusing on both shelf and deep water properties in the Gulf of Mexico. This
strategy is intended to generate sustained increases in production levels
through low to moderate risk exploration opportunities in the shelf area while
generating significant increases in reserves and production through our deep
water operations.

     Pursue Existing Exploration Opportunities.  We have currently identified 41
prospects which we intend to explore and develop over the next four years. These
prospects, especially those in the deep water, have the potential to provide
substantial increases in net proved reserves. We believe many of these prospects
offer significant opportunities at a lower cost as they are adjacent to existing
discoveries and can be developed utilizing existing infrastructure. In addition,
we are focused on replenishing our inventory of exploration opportunities by
utilizing the latest 2-D and 3-D seismic technology to generate new prospects.

                                       S-4
   5

     Maintain Low Cost Structure.  Our management team is focused on maintaining
a low cost structure in order to maximize cash flow. We believe we are able to
achieve low operating costs and general and administrative costs through
economies of scale and geographic focus. We believe that maintaining a low cost
structure permits us to remain consistently profitable in various pricing
environments.

     Pursue Selective Acquisitions.  We continually review potential
acquisitions of properties located in the Gulf Coast region. We target oil and
gas properties that have exploration and development potential in addition to
existing production and reserves.

RECENT EVENTS

     For the three month period ended March 31, 2001, our average production
increased 9% to 41.7 MMcfe per day from 38.2 MMcfe per day for the three month
period ended March 31, 2000. For the same periods, total revenues increased 106%
from $10.1 million in 2000 to $20.8 million in 2001.

                                  RISK FACTORS

     You should carefully consider all of the information we have included in
this prospectus supplement, the prospectus and the documents we have
incorporated by reference before purchasing our stock.

A DECREASE IN OIL AND GAS PRICES MAY ADVERSELY AFFECT OUR RESULTS OF OPERATIONS
AND FINANCIAL CONDITION.

     Our success is highly dependent on prices for oil and gas, which are
extremely volatile. Any substantial or extended decline in the price of oil or
gas would have a material adverse effect on us. Oil and gas markets are both
seasonal and cyclical. The prices of oil and gas depend on factors we cannot
control such as weather, economic conditions, levels of production, actions by
OPEC and other countries, and government actions. Prices of oil and gas will
affect the following aspects of our business:

     - our revenues, cash flows and earnings;

     - the amount of oil and gas that we are economically able to produce;

     - our ability to attract capital to finance our operations and the cost of
       the capital;

     - the amount we are allowed to borrow under our senior credit facility;

     - the value of our oil and gas properties; and

     - the profit or loss we incur in exploring for and developing our reserves.

A SIGNIFICANT PART OF THE VALUE OF OUR PRODUCTION AND RESERVES IS CONCENTRATED
IN A SMALL NUMBER OF OFFSHORE PROPERTIES, AND ANY PRODUCTION PROBLEMS OR
INACCURACIES IN RESERVE ESTIMATES RELATED TO THOSE PROPERTIES WOULD ADVERSELY
IMPACT OUR BUSINESS.

     For 2000, about 57% of our daily production came from three of our
properties in the Gulf of Mexico. Moreover, one property, consisting of six
wells and containing four reservoirs, accounted for 35% of our production during
this period. If mechanical problems, storms or other events curtailed a
substantial portion of this production, our results of operations would be
adversely affected. In addition, at December 31, 2000 most of our proved
reserves were located in 11 fields in the Gulf of Mexico, with approximately 90%
of our total net proved reserves attributable to five of these properties. If
the actual reserves associated with any one of these five discoveries are less
than our estimated reserves, our results of operations and financial condition
could be adversely affected.

UNLESS WE ARE ABLE TO REPLACE RESERVES WHICH WE HAVE PRODUCED, OUR CASH FLOWS
AND PRODUCTION WILL DECREASE OVER TIME.

     Our future success depends upon our ability to find, develop and acquire
oil and gas reserves that are economically recoverable. As is generally the case
for Gulf Coast properties, our producing properties usually have high initial
production rates, followed by a steep decline in production. As a result, we
must continually locate and develop or acquire new oil and gas reserves to
replace those being depleted by production. We must do this even during periods
of low oil and gas prices when it is difficult to raise the capital necessary to
finance these activities and during periods of high operating costs when it is
expensive to contract for drilling rigs and other equipment and personnel
necessary to explore for oil and gas. Without successful exploration or
acquisition activities, our reserves, production and revenues will decline
rapidly. We cannot assure you that we will be able to find and develop or
acquire additional reserves at an acceptable cost.

     Also, because of the relatively fast depletion rates of our properties, our
return on the investment we make in our oil and gas wells and the value of our
oil and gas wells will depend significantly on prices prevailing during
relatively short production periods.

OUR FOCUS ON EXPLORATION PROJECTS INCREASES THE RISKS INHERENT IN OUR OIL AND
GAS ACTIVITIES.

     Our business strategy focuses on replacing reserves through exploration,
where the risks are greater than in acquisitions and development drilling.
Although we have been successful in exploration in the past, we cannot assure
you that we will continue to increase reserves through exploration or at an
acceptable cost. Additionally, we are often uncertain as to the future costs and
timing of drilling, completing and producing wells. Our drilling operations may
be curtailed, delayed or canceled as a result of a variety of factors,
including:

     - unexpected drilling conditions;

     - pressure or inequalities in formations;

     - equipment failures or accidents;

     - adverse weather conditions;

     - compliance with governmental requirements; and

     - shortages or delays in the availability of drilling rigs and the delivery
       of equipment.

BECAUSE WE DO NOT CONTROL ALL OF OUR PROPERTIES, ESPECIALLY OUR DEEP WATER
PROPERTIES, WE HAVE LIMITED INFLUENCE OVER THEIR DEVELOPMENT.

     We do not operate all of our properties and have limited influence over the
operations of some of these properties, particularly our deep water projects.
Our lack of control could result in the following:

     - the operator may initiate exploration or development on a faster or
       slower pace than we prefer;

     - the operator may propose to drill more wells or build more facilities on
       a project than we have funds for or that we deem appropriate, which may
       mean that we are unable to participate in the project or share in the
       revenues generated by the project even though we paid our share of
       exploration costs; and

     - if an operator refuses to initiate a project, we may be unable to pursue
       the project.

Any of these events could materially reduce the value of our properties.

OUR DEEP WATER OPERATIONS HAVE SPECIAL RISKS THAT MAY NEGATIVELY AFFECT THE
VALUE OF THOSE ASSETS.

     Drilling operations in the deep water area are by their nature more
difficult and costly than drilling operations in shallow water. They require the
application of more advanced drilling technologies, involving a higher risk of
technological failure and usually resulting in significantly higher drilling
costs. Deep water wells are completed using subsea completion techniques that
require substantial time and the use of advanced remote installation equipment.
These operations involve a high risk of mechanical difficulties and equipment
failures that could result in significant cost overruns.

     In deep water, the time required to commence production following a
discovery is much longer than in shallow waters and on-shore. Our deep water
discoveries and prospects will require the construction of expensive production
facilities and pipelines prior to the beginning of production. We cannot
estimate the costs and timing of the construction of these facilities with
certainty, and the accuracy of our cost estimates will be affected by a number
of factors beyond our control, including the following:

     - decisions made by the operators of our deep water wells;

     - the availability of materials necessary to construct the facilities;

     - the proximity of our discoveries to pipelines; and

     - the price of oil and natural gas.

                                       S-10
   11

     Delays and cost overruns in the commencement of production will affect the
value of our deep water prospects and the discounted present value of reserves
attributable to those prospects.

COMPETITIVE INDUSTRY CONDITIONS MAY NEGATIVELY AFFECT OUR ABILITY TO CONDUCT
OPERATIONS.

     We operate in the highly competitive areas of oil and gas exploration,
development and production. We compete for the purchase of leases in the Gulf of
Mexico from the U.S. government and from other oil and gas companies. These
leases include exploration prospects as well as properties with proved reserves.
Factors that affect our ability to compete in the marketplace include:

     - our access to the capital necessary to drill wells and acquire
       properties;

     - our ability to acquire and analyze seismic, geological and other
       information relating to a property;

     - our ability to retain the personnel necessary to properly evaluate
       seismic and other information relating to a property;

     - the location of, and our ability to access, platforms, pipelines and
       other facilities used to produce and transport oil and gas production;

     - the standards we establish for the minimum projected return on an
       investment of our capital; and

     - the availability of alternate fuel sources.

     Our competitors include major integrated oil companies, substantial
independent energy companies, affiliates of major interstate and intrastate
pipelines and national and local gas gatherers, many of which possess greater
financial, technological and other resources than we do.

OUR COMPETITORS MAY USE SUPERIOR TECHNOLOGY WHICH WE MAY BE UNABLE TO AFFORD OR
WHICH WOULD REQUIRE COSTLY INVESTMENT BY US IN ORDER TO COMPETE.

     Our industry is subject to rapid and significant advancements in
technology, including the introduction of new products and services using new
technologies. As our competitors use or develop new technologies, we may be
placed at a competitive disadvantage, and competitive pressures may force us to
implement new technologies at a substantial cost. In addition, our competitors
may have greater financial, technical and personnel resources that allow them to
enjoy technological advantages and may in the future allow them to implement new
technologies before we can. We cannot be certain that we will be able to
implement technologies on a timely basis or at a cost that is acceptable to us.
One or more of the technologies that we currently use or that we may implement
in the future may become obsolete, and we may be adversely affected. For
example, marine seismic acquisition technology has been characterized by rapid
technological advancements in recent years, and further significant
technological developments could substantially impair our 3-D seismic data's
value.

WE MAY NOT BE ABLE TO REPLACE OUR RESERVES OR GENERATE CASH FLOWS IF WE ARE
UNABLE TO RAISE CAPITAL.

     We will be required to make substantial capital expenditures to develop our
existing reserves, and to discover new oil and gas reserves. Assuming this
offering and the note offering are completed, our current capital expenditure
plans include drilling 10 gross (2.4 net) development wells, including
sidetracks, and 20 gross (12.3 net) exploratory wells in the Gulf of Mexico deep
water and shelf areas through fiscal 2001. The estimated cost, net to us, to
drill and complete these wells is approximately $100.6 million which assumes
that a portion of these wells will be unsuccessful. If all of these wells are
successful, our estimated costs would be $133.0 million. The estimated dry hole
costs to drill these wells, which are the costs we would incur if all of the
wells were unsuccessful and we incurred no completion costs, are approximately
$45.3 million. Historically, we have financed these expenditures primarily with
cash from operations, proceeds from bank borrowings and proceeds from the sale
of debt and equity securities. We cannot assure you that we will be able to
raise capital in the future. We also make offers to acquire oil and gas
properties in the ordinary course of our business. If these offers are accepted,
our capital needs may increase substantially.
                                       S-11
   12

     We expect to continue using our senior credit facility to borrow funds to
supplement our available cash. The amount we may borrow under our senior credit
facility may not exceed a borrowing base. We cannot control the assumptions the
lenders use to calculate our borrowing base. The lenders may, without our
consent, adjust the borrowing base semiannually or in situations where we
purchase or sell assets or issue debt securities. If our borrowings under the
senior credit facility exceed the borrowing base, the lenders may require that
we repay the excess. If this were to occur, we might have to sell assets or seek
financing from other sources. Sales of assets could further reduce the amount of
our borrowing base. We cannot assure you that we would be successful in selling
assets or arranging substitute financing. If we were not able to repay
borrowings under our senior credit facility to reduce the outstanding amount to
less than the borrowing base, we would be in default under our senior credit
facility.

OUR DECISION TO DRILL A PROSPECT IS SUBJECT TO A NUMBER OF FACTORS AND WE MAY
DECIDE TO ALTER OUR DRILLING SCHEDULE OR NOT DRILL AT ALL.

     We describe our current prospects and our plans to explore these prospects
in this prospectus supplement, including the materials incorporated by
reference. A prospect is a property on which we have identified what our
geoscientists believe, based on available seismic and geological information, to
be indications of hydrocarbons. Our prospects are in various stages of
evaluation, ranging from a prospect which is ready to drill to a prospect which
will require substantial additional seismic data processing and interpretation.
Whether we ultimately drill a prospect may depend on the following factors:

     - receipt of additional seismic data or the reprocessing of existing data;

     - material changes in oil or gas prices;

     - the costs and availability of drilling rigs;

     - success or failure of wells drilled in similar formations or which would
       use the same production facilities;

     - availability and cost of capital;

     - changes in the estimates of the costs to drill or complete wells;

     - our ability to attract other industry partners to acquire a portion of
       the working interest to reduce exposure to costs and drilling risks; and

     - decisions of our joint working interest owners.

     We will continue to gather data about our prospects, and it is possible
that additional information may cause us to alter our drilling schedule or
determine that a prospect should not be pursued at all. You should understand
that our plans regarding our prospects are subject to change.

OUR RESERVE INFORMATION REPRESENTS ESTIMATES THAT MAY TURN OUT TO BE INCORRECT
IF THE ASSUMPTIONS UPON WHICH THESE ESTIMATES ARE BASED ARE INACCURATE.

     Estimating quantities of proved reserves is inherently imprecise and
involves uncertainties and factors beyond our control. The reserve data in this
prospectus supplement represent only estimates. These estimates are based upon
assumptions about future production levels, future oil and gas prices and future
operating costs. As a result, the quantity of our proved reserves may be subject
to downward or upward adjustment as additional information or analysis become
available. In addition, estimates of the economically recoverable oil and gas
reserves, classifications of such reserves, and estimates of future net cash
flows, prepared by different engineers or by the same engineers at different
times, may vary substantially. In particular, the assumptions regarding the
timing and costs to commence production from our deep water wells used in
preparing our reserves are subject to revisions over time as described under
"-- Our deep water operations have special risks that may negatively affect the
value of those assets." Information about reserves constitutes forward-looking
information. See "Forward-Looking Statements" for information regarding
forward-looking information. The discounted present value of our oil and gas
reserves is prepared in accordance with guidelines established by the SEC. A
valuation of reserves would

                                       S-12
   13

involve numerous other factors. The discounted present value of reserves,
therefore, does not represent the fair market value of those reserves.

     On December 31, 2000, approximately 58.2% of the discounted present value
of our estimated net proved reserves were proved undeveloped. Substantially all
of these proved undeveloped reserves were attributable to our deep water
properties. Development of these properties is subject to additional risks as
described above.

WEATHER, UNEXPECTED SUBSURFACE CONDITIONS, AND OTHER UNFORESEEN OPERATING
HAZARDS MAY ADVERSELY IMPACT OUR ABILITY TO CONDUCT BUSINESS.

     There are many operating hazards in exploring for and producing oil and
gas, including:

     - our drilling operations may encounter unexpected formations or pressures
       which could cause damage to equipment or personal injury;

     - we may experience equipment failures which curtail or stop production;
       and

     - we could experience blowouts or other damages to the productive
       formations that may require a well to be re-drilled or other corrective
       action to be taken.

     In addition, any of the foregoing may result in environmental damages for
which we will be liable. Moreover, a substantial portion of our operations are
offshore and are subject to a variety of risks particular to the marine
environment such as hurricanes and other adverse weather conditions. Offshore
operations are also subject to more extensive governmental regulation.

     We cannot assure you that we will be able to maintain adequate insurance at
rates we consider reasonable to cover our possible losses from operating
hazards. The occurrence of a significant event not fully insured or indemnified
against could materially and adversely affect our financial condition and
results of operations.

WE MAY NOT HAVE PRODUCTION TO OFFSET HEDGES; BY HEDGING, WE MAY NOT BENEFIT FROM
PRICE INCREASES.

     Part of our business strategy is to reduce our exposure to the volatility
of oil and gas prices by hedging a portion of our production. In a typical hedge
transaction, we will have the right to receive from the counterparties to the
hedge the excess of the fixed price specified in the hedge over a floating price
based on a market index, multiplied by the quantity hedged. If the floating
price exceeds the fixed price, we are required to pay the counterparties this
difference multiplied by the quantity hedged. We are required to pay the
difference between the floating price and the fixed price when the floating
price exceeds the fixed price regardless of whether we have sufficient
production to cover the quantities specified in the hedge. Significant
reductions in production at times when the floating price exceeds the fixed
price could require us to make payments under the hedge agreements even though
such payments are not offset by sales of production. Hedging will also prevent
us from receiving the full advantage of increases in oil or gas prices above the
fixed amount specified in the hedge. We also enter into price "collars" to
reduce the risk of changes in oil and gas prices. Under a collar, no payments
are due by either party so long as the market price is above a floor set in the
collar and below a ceiling. If the price falls below the floor, the counterparty
to the collar pays the difference to us and if the price is above the ceiling,
we pay the counterparty the difference.

COMPLIANCE WITH ENVIRONMENTAL AND OTHER GOVERNMENT REGULATIONS COULD BE COSTLY
AND COULD NEGATIVELY IMPACT PRODUCTION.

     Our operations are subject to numerous laws and regulations governing the
discharge of materials into the environment or otherwise relating to
environmental protection. These laws and regulations may:

     - require that we acquire permits before commencing drilling;

     - restrict the substances that can be released into the environment in
       connection with drilling and production activities;

                                       S-13
   14

     - limit or prohibit drilling activities on protected areas such as wetlands
       or wilderness areas; and

     - require remedial measures to mitigate pollution from former operations,
       such as dismantling abandoned production facilities.

     Under these laws and regulations, we could be liable for personal injury
and clean-up costs and other environmental and property damages, as well as
administrative, civil and criminal penalties. We maintain limited insurance
coverage for sudden and accidental environmental damages. We do not believe that
insurance coverage for environmental damages that occur over time is available
at a reasonable cost. Also, we do not believe that insurance coverage for the
full potential liability that could be caused by sudden and accidental
environmental damages is available at a reasonable cost. Accordingly, we may be
subject to liability or we may be required to cease production from properties
in the event of environmental damages.

FACTORS BEYOND OUR CONTROL AFFECT OUR ABILITY TO MARKET PRODUCTION AND OUR
FINANCIAL RESULTS.

     The ability to market oil and gas from our wells depends upon numerous
factors beyond our control. These factors include:

     - the extent of domestic production and imports of oil and gas;

     - the proximity of the gas production to gas pipelines;

     - the availability of pipeline capacity;

     - the demand for oil and gas by utilities and other end users;

     - the availability of alternative fuel sources;

     - the effects of inclement weather;

     - state and federal regulation of oil and gas marketing; and

     - federal regulation of gas sold or transported in interstate commerce.

     Because of these factors, we may be unable to market all of the oil or gas
we produce. In addition, we may be unable to obtain favorable prices for the oil
and gas we produce.

WE HAVE BEEN REQUIRED TO TAKE WRITEDOWNS OF THE CARRYING VALUE OF OUR OIL AND
GAS PROPERTIES IN THE PAST, AND MAY BE REQUIRED TO DO SO IN THE FUTURE, AS A
RESULT OF A DECREASE IN OIL AND GAS PRICES.

     During 1998 we were required to writedown the carrying value of our oil and
gas properties due to a significant decline in oil and gas prices. We may be
required to writedown the carrying value of our oil and gas properties in the
future if oil and gas prices decline or if we have substantial downward
adjustments to our estimated net proved reserves, increases in our estimates of
development costs or deterioration in our exploration results. Under the
full-cost method we use to account for our oil and gas properties, the net
capitalized costs of our oil and gas properties may not exceed the present
value, discounted at 10%, of future net cash flows from estimated net proved
reserves, using period end oil and gas prices and costs, plus the lower of cost
or fair market value of our unproved properties. If the net capitalized costs of
our oil and gas properties exceed this limit, we must charge the amount of the
excess to earnings. This type of charge will not affect our cash flows, but will
reduce the book value of our stockholders' equity. We review the carrying value
of our properties quarterly, based on prices in effect as of the end of each
quarter or at the time of reporting our results. Once incurred, a writedown of
oil and gas properties is not reversible at a later date, even if prices
increase.

OUR SIGNIFICANT DEBT LEVELS AND OUR DEBT COVENANTS MAY LIMIT OUR FUTURE
FLEXIBILITY IN OBTAINING ADDITIONAL FINANCING AND IN PURSUING BUSINESS
OPPORTUNITIES.

     Concurrent with the common stock offering, we are conducting an offering of
our senior notes. Assuming we had issued the notes and applied the proceeds as
described in "Use of Proceeds" as of

                                       S-14
   15

December 31, 2000, after giving pro forma effect to the offering and senior note
offering, we would have had $208.0 million in total debt. The level of our
indebtedness will have important effects on our future operations, including:

     - a portion of our cash flow will be used to pay interest and principal on
       our debt and will not be available for other purposes;

     - our senior credit facility contains financial tests which we must satisfy
       in order to continue to borrow funds under the facility, and a failure to
       meet these tests also may be a default under our senior credit facility;

     - covenants in the notes and in our existing senior subordinated notes
       require us to meet financial tests in order to borrow additional money,
       which may have the effect of limiting our flexibility in reacting to
       changes in our business and our ability to fund future operations and
       acquisitions;

     - our ability to refinance existing debt or to obtain additional financing
       for capital expenditures and other purposes may be limited;

     - we may be more leveraged than our competitors, which may place us at a
       competitive disadvantage; and

     - we may be unable to adjust rapidly to changing market conditions.

     These consequences could make us more vulnerable than a less leveraged
competitor in the event of a downturn in our business or general economic
conditions.

WE MAY NOT BE ABLE TO GENERATE SUFFICIENT CASH FLOW TO SERVICE OUR EXISTING
INDEBTEDNESS.

     At December 31, 2000, after giving pro forma effect to the offering and the
offering of senior notes, including the redemption of our notes due 2002 and
notes due 2004, we would have had total indebtedness of $208.0 million, and cash
and cash equivalents of $127.3 million. We intend to incur additional
indebtedness after the offering as we execute our business strategy.

     Our ability to make scheduled payments or to refinance our indebtedness,
including $33.0 million of our 11% senior subordinated notes due 2005, which we
do not intend to redeem with the proceeds of the offerings, and our senior
credit facility, depends on our future performance and successful implementation
of our strategy, both of which are subject not only to our actions but also to
general economic, financial, competitive, legislative and regulatory conditions,
the prevailing market prices for oil and gas and other factors beyond our
control.

                           FORWARD-LOOKING STATEMENTS

     In this prospectus supplement, we have made many forward-looking
statements. We cannot assure you that the plans, intentions or expectations upon

factors that could affect our operating results and performance. We urge you to
carefully consider these factors.

     When you consider our forward-looking statements, you should keep in mind
these risk factors and the other cautionary statements in this prospectus
supplement. Our forward-looking statements speak only as of the date made, and
we have no obligation to update these forward-looking statements.

                                USE OF PROCEEDS

     We expect to receive approximately $48.2 million of net proceeds from the
common stock offering and $168.3 million of net proceeds from the note offering,
after deducting fees and expenses. The net proceeds of the offerings will be
used to redeem our outstanding $36.0 million of 10.125% senior subordinated
notes due 2002 and our outstanding $40.0 million of 10.25% senior subordinated
notes due 2004, as well as to repay all borrowings under our senior credit
facility. The total cost to redeem the notes is $76.7 million, plus accrued
interest. The remaining proceeds, together with our cash flows and borrowings
under our senior credit facility, will be used to fund our remaining 2001 and a
substantial part of our 2002 anticipated capital expenditures. Our anticipated
capital expenditures for 2001 and 2002 include expenditures of approximately
$48.0 million for the completion costs and associated production facility at our
Medusa discovery. Our remaining capital expenditures will be used for
exploration and development in the shelf and deep water areas, development of
our other deep water discoveries and other general corporate purposes. As of
March 31, 2001, $31.0 million was outstanding under our senior credit facility.
The weighted average interest rate on borrowings under our senior credit
facility on December 31, 2000 was 8.53%. Our existing senior credit facility
matures on July 31, 2002. However, pursuant to the terms of our senior credit
facility, the maturity date of our senior credit facility will be extended to
July 31, 2004 upon the redemption of our 10.125% senior subordinated notes due
2002. Until we use the net proceeds of the offerings, we will invest the funds
in short-term, investment grade, interest-bearing securities.

     We have not in the past paid, and do not anticipate paying in the
foreseeable future, cash dividends on our common stock. Any future payment of
cash dividends will depend upon our results of operations, financial condition,
cash requirements and other factors deemed relevant by our board of directors.

                              SENIOR NOTE OFFERING

     We are also offering $175.0 million of our senior notes due 2008. We will
close this offering of senior notes at the same time we close the offering of
common stock. The closing of this offering of common stock is contingent on our
closing the offering of senior notes. The interest rate on the senior notes will
be determined by negotiations between us and the initial purchasers of the
senior notes. The senior notes are not registered under the Securities Act of
1933, and are being sold in reliance on the exemptions from registration under
the Securities Act provided by Rule 144A and Regulation S.

     The senior notes will be in the original principal amount of $175.0
million. The senior notes will rank equally as to payment with borrowings under
our senior credit facility and other senior indebtedness, and senior to our
subordinated notes and other subordinated indebtedness. The notes will mature on
or about May 1, 2008. We will not be permitted to redeem the senior notes until
approximately four years following issuance, and thereafter at redemption
premiums set forth in the notes. In addition, we will be entitled to redeem up
to 35% of the notes prior to approximately three years after issuance from the
proceeds of offerings of common stock at a redemption premium set forth in the
notes. The notes will not be convertible into our capital stock or have any
other equity conversion feature.

     The indenture for the senior notes will contain covenants customary in
non-investment grade note indentures. These covenants will limit our ability to
do the following, among other things:

     - incur indebtedness;

     - pay dividends to holders of our capital stock, repurchase our capital
       stock and subordinated notes, and to make similar restricted payments;

     - incur liens on our assets;

     - merge, consolidate or sell all or substantially all of our assets, or to
       adopt a plan of liquidation;

     - engage in transactions with our affiliates;

                                       S-18
   19

     - guaranty indebtedness of others; and

     - make acquisitions.

     We will be required to offer to repurchase the senior notes for 101% of the
outstanding principal amount, plus accrued interest, if a change of control
occurs. A change of control is defined as:

     - the acquisition by any person or group of beneficial ownership of more
       than 50% of the total voting power of our capital stock;

     - the date that our board of directors is not composed of a majority of
       persons who are currently on our board of directors, or who were
       appointed or nominated by persons who are currently on our board of
       directors;

     - the sale, lease or transfer of all or substantially all of our assets;
       and

     - the adoption of a plan of liquidation.

     We cannot assure you that we will have sufficient funds to repurchase the
notes upon a change of control.

                                  UNDERWRITING

     Under the terms and subject to the conditions contained in an underwriting
agreement dated May 10, 2001, we will sell to the underwriter, Johnson Rice &
Company, L.L.C., all of the shares of common stock offered hereby.

     We have been advised by the underwriter that it proposes to offer the
common stock for sale in one or more transactions (which may involve block
transactions) on the New York Stock Exchange or on other national securities
exchanges on which our common stock is traded, in the over-the-counter market,
through negotiated transactions, or otherwise, at market prices at the time of
sale, at prices related to prevailing market prices or at negotiated prices,
subject to prior sale when, as and if delivered to and accepted by the
underwriter. We have been advised by the underwriter that it proposes to offer
the common stock to the public initially at a price of $11.00 per share. The
following table shows the underwriting discount in connection with this
offering. The discount is the difference between the initial price to the public
and the amount the underwriter pays us for the shares. On a per share basis, the
underwriting discount is 3.5% of the initial price to the public.



                                                                               UNDERWRITING

Total.....................................................    $50,000,000       $1,750,000


     We have granted the underwriter an option, exercisable for 30 days after
the date of this prospectus supplement, to purchase up to an additional 681,818
shares of common stock at the public offering price, less the underwriting
discount, set forth on the cover page of this prospectus supplement. The
underwriter may exercise such option solely to cover over-allotments, if any,
made in connection with the sale of shares of common stock that the underwriter
has agreed to purchase.

     The underwriting agreement provides that the underwriter's obligation to
purchase shares of the common stock depends on the satisfaction of the
conditions contained in the underwriting agreement, and that if any of the
shares of common stock are purchased by the underwriter, all of the shares of
common stock must be purchased. The conditions contained in the underwriting
agreement include the condition that all the representations and warranties made
by us to the underwriter are true, that there has been no material adverse
change in our condition or in the financial markets and that we deliver to the
underwriter customary closing documents.

                                       S-19

     We have agreed to indemnify the underwriter against certain liabilities,
including liabilities under the Securities Act of 1933 and liabilities arising
from breaches of representations and warranties made by us in the underwriting
agreement, or to contribute to payments that may be required to be made in
respect of these liabilities.

     We have agreed, subject to certain conditions, that we will not, directly
or indirectly, sell, offer or otherwise dispose of any shares of common stock or
enter into any derivative transactions with similar effect as a sale of common
stock, for a period of 90 days after the date of this prospectus supplement
without the prior written consent of the underwriter.

     The underwriter may engage in stabilizing transactions in accordance with
Regulation M under the Exchange Act. Stabilizing transactions permit bids to
purchase the underlying security so long as the stabilizing bids do not exceed a
specified maximum. These stabilizing transactions may cause the price of the
common stock to be higher that it would otherwise be in the absence of these
transactions, may be effected on the New York Stock Exchange or otherwise and,
if commenced, may be discontinued at any time.

                                 LEGAL MATTERS

     Certain legal matters with respect to the common stock will be passed upon
for us by Haynes and Boone, LLP. Certain legal matters in connection with this
offering will be passed upon for the underwriter by Jones, Walker, Waechter,
Poitevent, Carrere & Denegre, L.L.P., New Orleans, Louisiana.

                                    EXPERTS

     Our audited consolidated financial statements, as of December 31, 2000, and
for each of the years in the three-year period ended December 31, 2000, have
been incorporated by reference herein in reliance upon the report, incorporated
by reference herein, of Arthur Andersen, LLP, independent certified public
accountants, and upon the authority of such firm as experts in accounting and

     The information appearing and incorporated by reference in this prospectus
supplement regarding our quantities of oil and gas and future net cash flows and
the present values therof from such reserves is based on estimates of such
reserves and present values prepared by Huddleston & Co., Inc., an independent
petroleum and geological engineering firm and are included herein in reliance
upon their authority as experts in estimating reserves and present values.

                         GLOSSARY OF OIL AND GAS TERMS

TERMS USED TO DESCRIBE QUANTITIES OF OIL AND NATURAL GAS

     Bbl -- One stock tank barrel, or 42 US gallons liquid volume, of crude oil
or other liquid hydrocarbons.

     Bcf -- One billion cubic feet of natural gas.

     Bcfe -- One billion cubic feet of natural gas equivalent, computed on an
appropriate energy equivalent basis that one Bbl equal six Mcf.

     BOE -- One barrel of oil equivalent, converting gas to oil at the ratio of
six Mcf of gas to one Bbl of oil.

     MBbl -- One thousand Bbls.

     Mcf -- One thousand cubic feet of natural gas.

     Mcfe -- One thousand cubic feet of natural gas equivalent, computed on an
approximate energy equivalent basis that one Bbl equals six Mcf.

                                       S-20
   21

     MMcf -- One million cubic feet of natural gas.

     MMcfe -- One million cubic feet of natural gas equivalent, computed on an
approximate energy equivalent basis that one Bbl equals six Mcf.

TERMS USED TO DESCRIBE OUR INTERESTS IN WELLS AND ACREAGE

     Gross oil and gas wells or acres -- Our gross wells or gross acres
represents the total number of wells or acres in which we own a working
interest.

     Net oil and gas wells or acres -- Determined by multiplying "gross" oil and
natural gas wells or acres by the working interest that we own in such wells or
acres represented by the underlying properties.

TERMS USED TO ASSIGN A PRESENT VALUE TO OUR RESERVES

     Standardized measure of proved reserves -- The present value, discounted at
10%, of the after tax net cash flows attributable to estimated net proved
reserves. We calculate this amount by assuming that we will sell the oil and gas
production attributable to the proved reserves estimated in our independent
engineer's reserve report for the prices we received for the production on the
date of the report, unless we had a contract to sell the production for a
different price. We also assume that the cost to produce the reserves will
remain constant at the costs prevailing on the date of the report. The assumed
costs are subtracted from the assumed revenues resulting in a stream of future
net cash flows. Estimated future income taxes using rates in effect on the date
of the report are deducted from the net cash flow stream. The after-tax cash
flows are discounted at 10% to result in the standardized measure of our proved
reserves. The standardized measure of our proved reserves is disclosed in our
audited financial statements at note 12.

     Pre-tax discounted present value -- The discounted present value of proved
reserves is identical to the standardized measure, except that estimated future
income taxes are not deducted in calculating future net cash flows. We disclose
the discounted present value without deducting estimated income taxes to provide
what we believe is a better basis for comparison of our reserves to other
producers who may have different tax rates.

TERMS USED TO CLASSIFY OUR RESERVE QUANTITIES

     The Securities and Exchange Commission definition of proved oil and gas
reserves, per Article 4-10(a)(2) of Regulation S-X, is as follows:

          Proved oil and gas reserves.  Proved oil and gas reserves are the
     estimated quantities of crude oil, natural gas, and natural gas liquids
     which geological and engineering data demonstrate with reasonable certainty
     to be recoverable in future years from known reservoirs under existing
     economic and operating conditions, i.e., prices and costs as of the date
     the estimate is made. Prices include consideration of changes in existing
     prices provided only by contractual arrangements, but not on escalations
     based upon future conditions.

          (a) Reservoirs are considered proved if economic producibility is
     supported by either actual production or conclusive formation test. The
     area of a reservoir considered proved includes (A) that portion delineated
     by drilling and defined by gas-oil and/or oil-water contacts, if any; and
     (B) the immediately adjoining portions not yet drilled, but which can be
     reasonably judged as economically productive on the basis of available
     geological and engineering data. In the absence of information on fluid
     contacts, the lowest known structural occurrence of hydrocarbons controls
     the lower proved limit of the reservoir.

          (b) Reserves which can be produced economically through application of
     improved recovery, techniques (such as fluid injection) are included in the
     "proved" classification when successful testing by a pilot project, or the
     operation of an installed program in the reservoir, provides support for
     the engineering analysis on which the project or program was based.

                                       S-21
   22

          (c) Estimates of proved reserves do not include the following: (1) oil
     that may become available from known reservoirs but is classified
     separately as "indicated additional reserves"; (2) crude oil, natural gas,
     and natural gas liquids, the recovery of which is subject to reasonable
     doubt because of uncertainty as to geology, reservoir characteristics, or
     economic factors; (3) crude oil, natural gas, and natural gas liquids, that
     may occur in undrilled prospects; and (4) crude oil, natural gas, and
     natural gas liquids, that may be recovered from oil shales, coal, gilsonite
     and other such sources.

     Proved developed reserves -- Proved reserves that can be expected to be
recovered through existing wells with existing equipment and operating methods.

     Proved undeveloped reserves -- Proved reserves that are expected to be
recovered from new wells on undrilled acreage, or from existing wells where a
relatively major expenditure is required.

TERMS WHICH DESCRIBE THE COST TO ACQUIRE OUR RESERVES

     Reserve replacement costs -- Our reserve replacement costs compare the
amount we spent to explore for oil and gas and to drill and complete wells
during a period, with the increases in reserves during the period. This amount
is calculated by dividing the net change in our evaluated oil and property costs
during a period by the change in proved reserves plus production over the same
period.

TERMS WHICH DESCRIBE THE PRODUCTIVE LIFE OF A PROPERTY OR GROUP OF PROPERTIES

     Reserve life -- A measure of the productive life of an oil and gas property
or a group of oil and gas properties, expressed in years. Reserve life equals
the estimated net proved reserves attributable to a property or group of
properties divided by production from the property or group of properties for
the four fiscal quarters preceding the date as of which the proved reserves were
estimated.

TERMS USED TO DESCRIBE THE LEGAL OWNERSHIP OF OUR OIL AND GAS PROPERTIES

     Royalty interest -- A real property interest entitling the owner to receive
a specified portion of the gross proceeds of the sale of oil and natural gas
production or, if the conveyance creating the interest provides, a specific
portion of oil and natural gas produced, without any deduction for the costs to
explore for, develop or produce the oil and natural gas. A royalty interest
owner has no right to consent to or approve the operation and development of the
property, while the owners of the working interests have the exclusive right to
exploit the mineral on the land.

     Working interest -- A real property interest entitling the owner to receive
a specified percentage of the proceeds of the sale of oil and natural gas
production or a percentage of the production, but requiring the owner of the
working interest to bear the cost to explore for, develop and produce such oil
and natural gas. A working interest owner who owns a portion of the working
interest may participate either as operator or by voting his percentage interest
to approve or disapprove the appointment of an operator and drilling and other
major activities in connection with the development and operation of a property.

TERMS USED TO DESCRIBE SEISMIC OPERATIONS

     Seismic data -- Oil and gas companies use seismic data as their principal
source of information to locate oil and gas deposits, both to aid in exploration
for new deposits and to manage or enhance production from known reservoirs. To
gather seismic data, an energy source is used to send sound waves into the
subsurface strata. These waves are reflected back to the surface by underground
formations, where they are detected by geophones which digitize and record the
reflected waves. Computers are then used to process the raw data to develop an
image of underground formations.

     2-D seismic data -- 2-D seismic survey data has been the standard
acquisition technique used to image geologic formations over a broad area. 2-D
seismic data is collected by a single line of energy sources which reflect
seismic waves to a single line of geophones. When processed, 2-D seismic data
produces an image of a single vertical plane of sub-surface data.

                                       S-22
   23

     3-D seismic -- 3-D seismic data is collected using a grid of energy
sources, which are generally spread over several miles. A 3-D survey produces a
three dimensional image of the subsurface geology by collecting seismic data
along parallel lines and creating a cube of information that can be divided into
various planes, thus improving visualization. Consequently, 3-D seismic data is
a more reliable indicator of potential oil and natural gas reservoirs in the
area evaluated.

                         ABOUT CALLON PETROLEUM COMPANY

     We have been engaged in the exploration, development, acquisition and
production of oil and gas properties since 1950. Our properties are
geographically concentrated offshore in the Gulf of Mexico, where we have
substantial experience. Since 1996, our primary focus has been on acquiring
exploration prospects, conducting 3-D and conventional 2-D seismic surveys of
these prospects and drilling exploration wells. We have assembled a balanced
portfolio of exploration projects in the Gulf of Mexico composed of:

     - controlling working interests in projects with low exploration risk and
       low drilling and completion costs targeting reserve deposits of between
       three and 10 Bcf in the shallow Miocene area at depths of less than 4,000
       feet;

     - significant working interest in projects with higher exploration risk and
       higher drilling and completion costs targeting reserve deposits of
       between 10 and 100 Bcfe in the outer continental shelf area at depths of
       between 7,000 and 17,000 feet; and

     - small working interest in projects with high exploration risk and high
       drilling and completion cost targeting reserve deposits in the deep water
       area of the Gulf of Mexico.

     Our principal executive offices are located at 200 North Canal Street,
Natchez, Mississippi 39120 and our telephone number is (601) 442-1601.

                                USE OF PROCEEDS

     Unless otherwise set forth in the applicable prospectus supplement,
proceeds from the sale of the securities sold by us will be used for general
corporate purposes. These purposes may include acquisitions, working capital,
capital expenditures, the repurchase of outstanding securities and the repayment
of indebtedness. Proceeds from the sale of securities initially may be
temporarily invested in short-term securities.

              RATIOS OF EARNINGS TO FIXED CHARGES AND OF EARNINGS
            TO COMBINED FIXED CHARGES AND PREFERRED STOCK DIVIDENDS

     Our ratios of earnings to fixed charges and of earnings to combined fixed
charges and preferred stock dividends for the periods indicated below as
calculated under generally accepted accounting principles are as follows:



                                                   YEAR ENDED DECEMBER 31,        SIX MONTHS ENDED

Ratio of earnings to combined fixed charges
  and preferred stock dividends..............   --    1.3    1.2    1.7     --           --


     When we calculate our ratio of earnings to fixed charges, "earnings" are
composed of the following:

     - consolidated earnings or loss from continuing operations before tax,
       excluding undistributed equity earnings or affiliated companies; plus

     - fixed charges, excluding capitalized interest.

     Fixed charges are comprised of the following:

     - interest expense on indebtedness and capitalized interest;

     - amortization of debt issuance costs, discounts and premiums; and

     - the portion of capitalized leases deemed to be representative of
       interest.

     Earnings did not cover fixed charges by $679,000 through the second quarter
of 1999, $50.3 million in 1998 and $313,000 in 1994.

     In calculating the ratio of earnings to combined fixed charges and
preferred stock dividends, fixed charges include pre-tax preferred stock
dividend requirements.

     Earnings did not cover combined fixed charges and preferred stock dividends
by $2.7 million through the second quarter of 1999, $54.5 million in 1998 and
$313,000 in 1994.

                         DESCRIPTION OF DEBT SECURITIES

     The debt securities will be our direct unsecured obligations. The debt
securities will be either senior debt securities or subordinated debt
securities. The debt securities will be issued under one or more indentures
between us and a trustee that we will name in the prospectus supplement. Senior
debt securities will be issued under a "senior indenture" and subordinated debt
securities will be issued under a "subordinated indenture." Together, we refer
to the senior indenture and subordinated indenture as the "indentures."

     We have not restated the indentures in their entirety. We filed the forms
of the indentures as exhibits to our registration statement. You should read the
indentures because they, and not this description, will control your rights as
holders of debt securities. In the summary below, we have included references to
section numbers of the applicable indentures so that you can easily locate these
provisions. Capitalized terms used in the summary have the meanings specified in
the indentures.

     Unless otherwise specifically noted in the following discussion, references
to "we," "us" or "our" means Callon Petroleum Company without its subsidiaries.

                                        3
   29

     We have summarized the material provisions of the indentures in the
following order:

     - those applicable to both indentures; and

     - those applicable only to the subordinated indenture.

PROVISIONS APPLICABLE TO BOTH SENIOR AND SUBORDINATED DEBT SECURITIES

  General

     The debt securities described in a prospectus supplement will be our
unsecured, senior or subordinated obligations. The senior debt securities will
rank equally with all of our other unsecured and unsubordinated debt, and will
rank senior to our subordinated debt. The subordinated debt securities will have
a junior position to our senior indebtedness. Subordinated debt securities may
rank equally with or junior to our existing subordinated indebtedness. The terms
of subordination are described below under "Provisions Applicable Solely to
Subordinated Debt Securities -- Subordination" and may be further described or
changed in a prospectus supplement.

     A prospectus supplement relating to any series of debt securities that we
offer will include specific terms relating to that series. These terms will
include, among other things, some or all of the following:

     - the title of the debt securities;

     - the total principal amount;

     - whether they are senior debt securities or subordinated debt securities;

     - if they are subordinated debt securities, the terms of subordination if
       different from those described below;

     - whether the series of debt securities are issuable as registered
       securities, bearer securities or both;

     - whether any debt securities of the series are to be issuable in temporary
       or permanent global form with or without coupons, and whether permanent
       global securities may be exchanged for securities of such series;

     - the person to whom any interest on any series shall be payable;

     - the dates on which principal and any premium on the debt securities will
       be payable;

     - the interest rate or the method used to determine the interest rate,
       record and interest payment dates;

     - whether and under what circumstances any additional amounts with respect
       to the debt securities will be payable;

     - the place or places where payments on the debt securities are payable or
       the method of payment and where the debt securities may be surrendered
       for transfer or exchange;

     - any optional redemption provisions;

     - any sinking fund or other provisions that would obligate us to repurchase
       or otherwise redeem the series of debt before final maturity;

     - the denominations in which the debt securities will be issuable;

     - whether payments on the debt securities will be payable in foreign
       currency or currency units or another form, and whether payments will be
       payable by reference to any index or formula;

     - the portion of the principal amount of debt securities that will be
       payable if the maturity is accelerated, if other than the entire
       principal amount;

     - whether the securities of the series will be issued in the form of
       book-entry securities, the depositary for such series, and the
       circumstances for exchanging such book-entry securities for certificated
       securities;

     - any means of defeasance on the debt securities and any additional
       conditions or limitations to defeasance of the debt securities;

     - any changes to or additional events of default or covenants;

     - if the principal amount payable at the stated maturity of any securities
       will not be determinable at any time prior to the stated maturity, the
       amount which shall be deemed to be the principal amount of such
       securities as of any such time;

                                        4
   30

     - any restriction or condition on the transfer or exchange of the debt
       securities;

     - any rights that we may have to defer payments of interest;

     - any terms for the conversion or exchange of the debt securities for other
       securities of ours or any other entity; and

     - any other terms of the series of debt securities.

     A series of debt securities may be issued with an original issue discount.
An original issue discount provides that less than the entire principal amount
of the series of debt securities is payable upon declaration of acceleration of
the maturity of the series of debt securities. Special U.S. federal income tax
considerations may be applicable to debt securities issued at an original issue
discount. These special considerations will be set forth in a prospectus
supplement relating to the series of debt securities.

     The indentures do not limit the amount of debt securities or other types of
indebtedness we may issue. The indentures allow debt securities to be issued up
to any principal amount that we may authorize. The subordinated indenture allows
us to issue subordinated debt securities which are convertible into other
securities, including shares of our common stock or preferred stock.

     Debt securities may be issued in certificated or global form. (Sections
201, 203 and 301)

  Information about the Trustee

     The trustee may resign at any time. The prospectus supplement will describe
any rights the holders of a series of debt securities have to remove the
trustee. Under the Trust Indenture Act of 1939, as amended, governing trustee
conflicts of interest, any uncured Event of Default with respect to any series
of senior debt securities will force the trustee to resign as trustee under
either the subordinated indenture or the senior indenture. Similarly, any
uncured Event of Default with respect to any series of subordinated debt
securities will force the trustee to resign as trustee under either the senior
indenture or subordinated indenture. If the trustee resigns, is removed or
becomes incapable of acting as trustee, a successor trustee will have to be
appointed in accordance with the provisions of the applicable indenture.

  Denominations

     The prospectus supplement for each series of debt securities will state
whether we will issue the debt securities in registered form or in bearer form.

  Modification of Indentures; Waiver of Covenants

     We generally may amend the indentures or the debt securities with the
written consent of a majority in principal amount of the outstanding debt
securities of each series affected by the amendment, with each series voting
separately as a class. The holders of a majority in principal amount of the
outstanding debt securities of any series may also waive our compliance with any
provision of the indentures with respect to debt securities of that series. We
must, however, obtain the consent of each holder of debt securities affected by
an amendment or waiver which does, among other things, any of the following:

     - changes the stated maturity of, or any installment of principal of or
       interest on, any debt securities;

     - reduces the principal amount of, or rate of interest or premium payable
       on, any debt securities;

     - reduces the amount of the principal of an original issue discount
       security or other security which would be payable upon acceleration of
       the debt securities;

     - adversely affects any right of repayment at the option of a holder of any
       debt security;

     - reduces the amount of, or postpones the date fixed for, the payment of
       any sinking fund or analogous obligation;

     - changes the place of payment where, or the currency in which, any debt
       security is payable;

     - impairs the right to institute suit for the enforcement of any payment on
       or after the stated maturity date of any debt security; or

     - reduces the percentage of holders required to consent to any supplements,
       modifications, waivers or amendments to the indentures. (Section 902)
                                        5
   31

     Additionally, the subordinated indenture may not be modified to alter the
terms of subordination of any outstanding series of subordinated debt securities
without the consent of the holder of senior indebtedness that would be adversely
affected by the modification. (Section 907 of the subordinated indenture)

     If we issue convertible subordinated debt securities, the terms of
conversion may not be modified in a manner which is adverse to the holders of
the convertible subordinated debt securities without the consent of such
holders. (Section 902 of the subordinated indenture)

     If we issue a series of debt securities with an original issue discount or
with a principal amount that is not fixed, the applicable prospectus supplement
will describe the manner in which we will determine whether holders of a
majority of principal amount of a series of debt securities have approved a
modification or waiver of a provision of an indenture.

     We may amend the indentures or outstanding debt securities without notice
to or consent from any holder of the debt security to do, among other things,
any of the following:

     - permit a successor corporation to assume our obligations under the
       indenture following a merger, consolidation or similar transaction;

     - add to our covenants for the benefit of the holders of any series of debt
       securities;

     - add additional events of default for the benefit of the holders of all or
       any series of securities;

     - accept the appointment of a successor trustee of one or more series and
       to provide for more than one trustee, if applicable;

     - cure any ambiguity, defect or inconsistency;

     - secure debt securities issued pursuant to the indentures;

     - provide that bearer securities may be registrable as to principal, amend
       restrictions on the payment of principal, premiums or interest on bearer
       securities, or permit bearer securities to be issued in exchange for
       registered securities or bearer securities of other authorized
       denominations;

     - amend any provision of an indenture in a manner that does not apply to,
       or modify the rights of holders of, any debt securities outstanding at
       the time and entitled to rely on the provision;

     - provide for uncertificated securities of any series;

     - comply with the requirements of the SEC in order to effect or maintain
       the qualification of the indentures under the Trust Indenture act; or

     - make any change that does not adversely affect the interests of any
       holder of outstanding debt securities. (Section 901)

  Meetings of Holders of Debt Securities

     Each indenture contains provisions for convening meetings of the holders of
a series if debt securities of that series are issuable as bearer securities.
(Section 1401) A meeting may be called at any time by the Trustee, by our board
of directors or the holders of at least 10% in aggregate principal amount of the
outstanding securities of such series. (Section 1402) Except for any consent
which must be given by the holder of each outstanding security affected thereby,
as described above, any resolution presented at a meeting (or adjourned meeting
at which a quorum is present) may be adopted by the affirmative vote of the
holders of a majority in aggregate principal amount of the outstanding
securities of that series; provided, however, that any resolution with respect
to any request, demand, authorization, direction, notice, consent, waiver or
other action which may be made, given or taken by the holders of a specified
percentage which is less than a majority in aggregate principal amount of the
outstanding securities of a series may be adopted at a meeting (or adjourned
meeting duly reconvened at which a quorum is present) by the affirmative vote of
the holders of such specified percentage in aggregate principal amount of the
outstanding securities of that series. Any resolution passed or decision taken
at any meeting of holders of any series duly held in accordance with the
applicable indenture will be binding on all holders of that series and related
coupons. The quorum at any meeting, and at any reconvened meeting, will be
persons holding or representing a majority in aggregate principal amount of the
outstanding securities of a series. (Section 1404)

                                        6
   32

  No Protection if a Change of Control Occurs

     Unless we otherwise state in a prospectus supplement, the debt securities
will not contain any provision which may allow holders of debt securities the
right to require us to repurchase the debt securities if a change of control
occurs or if we engage in a transaction which materially increases our leverage.
A change of control or a highly leveraged transaction could adversely affect the
holders of debt securities.

  Events of Default

     Unless we inform you otherwise in the prospectus supplement, "Event of
Default" means any of the following (Section 501):

     - failure to pay the principal of or any premium on any debt security when
       due;

     - failure to pay interest on any debt security within 30 days after due;

     - failure to deposit any sinking fund payment within 30 days after due;

     - failure to perform, or breach of, any other covenant in the indenture
       (other than an agreement or covenant that we have included in the
       indenture solely for the benefit of other series of debt securities) that
       continues for 90 days after we are given written notice;

     - our bankruptcy, insolvency or reorganization; or

     - any other Event of Default for that series of debt securities described
       in the applicable prospectus supplement.

     An Event of Default for a particular series of debt securities may, but
does not necessarily, constitute an Event of Default for any other series of
debt securities.

     If an Event of Default for any series of debt securities occurs and
continues, the trustee or the holders of at least 25% in aggregate principal
amount of the debt securities of the series may declare the entire principal of
all the debt securities of that series to be due and payable immediately. If
this happens, subject to certain exceptions, the holders of a majority of the
aggregate principal amount of the debt securities of that series can void the
declaration. (Section 502).

     The indentures provide that a holder of a series of debt securities may not
file a lawsuit or otherwise institute proceedings under the indenture or appoint
a receiver or trustee unless the following happens:

     - the holders give the trustee written notice;

     - the holders of 25% of the series of debt securities also give such notice
       and offer reasonable indemnification to the trustee;

     - the holders of at least a majority of the aggregate principal amount of
       the series of debt securities do not give an inconsistent notice; and

     - the trustee does not institute the proceeding within 60 days of the
       demand. (Section 507).

     The four requirements listed above do not apply to proceedings instituted
by a holder of a series of debt securities to enforce the payment of principal,
premium or interest. (Section 508).

     If we issue a series of debt securities with an original issue discount,
the prospectus supplement will describe the amount a holder of the debt
securities is entitled to receive if the series of debt securities is declared
due and payable.

     The trustee is not obligated to exercise any of its rights or powers under
an indenture at the request or direction of any holders, unless the holders
offer the trustee reasonable indemnity against costs, expenses and liabilities.
(Section 602). If they provide this reasonable indemnification, the holders of a
majority in aggregate principal amount of the outstanding debt securities of any
series may direct the time, method and place of conducting any proceeding or any
remedy available to the trustee, or exercising any power conferred upon the
trustee, for any series of debt securities. The trustee is not required to take
action which the trustee determines is prejudicial to the holders of the series
of debt securities who do not request the trustee to take the action, or which
may cause the trustee to have personal liability. (Sections 512 and 601).

  Covenants

     Under the indentures, we have agreed, among other things, to:

     - pay the principal of and any interest and any premium on the debt
       securities when due (Section 1001);

     - maintain a place of payment (Section 1002);

     - deposit sufficient funds with the paying agent on or before the due date
       for any principal, interest or any premium payment or, if we act as our
       own paying agent, segregate such funds and hold them in trust for the
       benefit of the holders of the debt securities (Section 1003);

     - make all payments on the debt securities to holders who are United States
       aliens without withholding for any taxes or other governmental charges,
       if the debt securities of a series so provides; provided that if we are
       required to make any such withholding, we will pay the additional amount
       of such withholding to such holders (Section 1004); and

     - deliver a report to the trustee at the end of each fiscal year reviewing
       our obligations under the indenture (Section 1006).

  Consolidation, Merger or Sale

     The indentures generally permit us to consolidate or merge with or sell,
transfer or lease all or substantially all of our assets to another entity if we
comply with the terms and conditions of the indentures relating to such a
transaction, which include the following:

     - the remaining or acquiring entity (if other than us) must (i) be formed
       in a U.S. jurisdiction and (ii) assume all of our responsibilities and
       liabilities under the indentures including the payment of all amounts
       payable on the debt securities and performance of all the covenants in
       the indentures;

     - the transaction must not cause a default or event of default to occur;
       and

     - we must deliver to the trustee a certificate signed by certain of our
       officers and an opinion of counsel stating that the transaction complies
       with the indentures.

     The remaining or acquiring entity will be substituted for us in the
indentures with the same effect as if it had been an original party to the
indentures. Thereafter, our successor may exercise our rights and powers under
the indentures, in our name or in its own name. Any act or proceeding required
or permitted to be done by our board of directors or any of our officers may be
done by the board or officers of the successor entity. If we sell all or
substantially all of our assets, we will be released from all our liabilities
and obligations under the indentures and under the debt securities. (Sections
801 and 803).

  Defeasance

     When we use the term defeasance, we mean discharge from some or all of our
obligations under an indenture. The following discussion of legal defeasance and
covenant defeasance (Sections 1301 to 1306) will be applicable to a series of
debt securities (other than convertible subordinated debt securities) only if we
choose to have them apply to that series.

  Legal Defeasance

     If we provide in an applicable prospectus supplement, and as long as we
take steps to make sure that you receive all or your payments under the debt
securities of that series and are able to transfer the debt securities of that
series, we can elect to legally release ourselves from any obligations on such
series of debt securities (such a release is called "legal defeasance") other
than:

     - the rights of holders of outstanding notes to receive payments in respect
       of the principal of and premium and interest on the debt securities when
       these payments are due;

     - our obligation to replace any temporary debt securities, register the
       transfer or exchange of any debt securities, replace mutilated, lost or
       stolen debt securities, compensate and reimburse the trustee, remove and
       appoint a successor trustee, maintain an office or agency for payments in
       respect of the debt securities and qualify the indenture under the Trust
       Indenture Act;

                                        8
   34

     - the rights, powers, trusts, duties and immunities of the trustee; and

     - the legal defeasance provisions of the indentures. (Section 1304)

     In order for us to accomplish legal defeasance, the following must occur:

     - We must irrevocably deposit with the trustee cash and/or U.S. government
       and/or U.S. government agency securities that will generate enough cash
       to make interest, principal and any other payments on such debt
       securities on their various due dates.

     - Such defeasance shall not cause the trustee to have a conflict of
       interest.

     - There must be a change in current U.S. federal tax law or an IRS ruling
       that lets us make that deposit without causing you to be taxed on the
       debt securities any differently than if we did not make the deposit and
       just repaid the debt securities ourselves. Under current U.S. federal tax
       law, the deposit and our legal release from the securities would be
       treated as though we took back your debt securities and gave you your
       share of the cash and notes or bonds deposited in trust. In that event,
       you could recognize gain or loss on the debt securities you give back to
       us.

     - We must deliver to the trustee a legal opinion of our counsel confirming
       the tax law change described above and that all of the conditions to
       legal defeasance in the indenture have been satisfied.

     We will not be able to achieve legal defeasance if there is a continuing
default or event of default under the indentures or if doing so would violate
any other material agreement to which we are a party. (Section 1304). If we ever
were to accomplish legal defeasance as described above, you would have to rely
solely on the trust deposit for repayment of the debt securities. You could not
look to us for repayment in the unlikely event of any shortfall.

  Covenant Defeasance

     Under current U.S. federal tax law, we can make the same type of deposit
described above and be released from certain covenants relating to a series of
debt securities. The release from these covenants is called covenant defeasance.
In that event, you would lose the protection of these covenants but would gain
the protection of having money and/or securities set aside in trust to repay the
series of debt securities. We may not defease an obligation, if any, to convert
a series of debt securities into shares of our common stock, preferred stock or
other securities as provided in the subordinated indenture. In order to achieve
covenant defeasance, we must do the following:

     - We must deposit in trust for the benefit of all holders of the series of
       debt securities cash and/or U.S. government or U.S. government agency
       securities that will generate enough cash to make interest, principal and
       any other payments on the debt securities on their various due dates.

     - We must deliver to the trustee a legal opinion of our counsel confirming
       that under current U.S. federal tax law we may make that deposit without
       causing you to be taxed on the debt securities any differently than if we
       did not make the deposit and just repaid the debt securities ourselves.
       The opinion also must state that all of the conditions to covenant
       defeasance in the indenture have been fulfilled.

     Further, such defeasance may not cause the trustee to have a conflict of
interest.

     We will not be able to achieve covenant defeasance if there is a continuing
default or event of default under the indenture or if doing so would violate any
other material agreements to which we are a party. The indenture describes the
types of covenants we may fail to comply with without causing an event of
default if we accomplish covenant defeasance. (Section 1303).

     If we elect to make a deposit resulting in covenant defeasance, the amount
of money and/or U.S. government or U.S. government agency securities deposited
in trust should be sufficient to pay amounts due on the debt securities at the
time of their maturity. However, if the maturity of the debt securities is
accelerated due to the occurrence of an event of default, the amount in trust
may not be sufficient to pay all amounts due on the debt securities. We would
remain liable for
                                        9
   35

the shortfall as described in the applicable indenture.

  Form, Exchange, Registration and Transfer

     We may issue debt securities of a series in definitive form solely as
registered securities, solely as bearer securities or as both registered
securities and bearer securities. Unless we otherwise indicate in an applicable
prospectus supplement, bearer securities will have interest coupons attached.
(Section 201) The indentures also provide that debt securities of a series may
be issuable in temporary or permanent global form. (Section 201)

     Registered securities of any series will be exchangeable for other
registered securities of the same series of any authorized denominations and of
a like aggregate principal amount and tenor. In addition, if debt securities of
any series are issuable as both registered securities and bearer securities, at
the option of the holder, and subject to the terms of the applicable indenture,
bearer securities (with all unmatured coupons, except as provided below, and all
matured coupons in default) of such series will be exchangeable for registered
securities of the same series of any authorized denominations and of a like
aggregate principal amount and tenor. Bearer securities surrendered in exchange
for registered securities between a regular record date or a special record date
and the relevant date for payment of interest shall be surrendered without the
coupon relating to such date for payment of interest, and interest accrued as of
such date will not be payable in respect of the registered security issued in
exchange for such bearer security, but will be payable only to the holder of
such coupon when due in accordance with the terms of the applicable indenture.
Unless we otherwise provide with respect to any series of debt securities,
bearer securities will not be issued in exchange for registered securities.
(Section 305)

     Debt securities may be presented for exchange as provided above, and
registered securities may be presented for registration of transfer (with the
form of transfer endorsed thereon duly executed), at the office of the security
registrar or at the office of any transfer agent designated by us for such
purpose with respect to any series of debt securities and referred to in an
applicable prospectus supplement, without service charge and upon payment of any
taxes and other governmental charges as described in the indentures. Such
transfer or exchange will be effected upon the security registrar or such
transfer agent, as the case may be, being satisfied with the documents of title
and identity of the person making the request. The Trustee will serve initially
as security registrar for purposes of registering registered securities and
transfers of registered securities. (Section 305) If a prospectus supplement
refers to any transfer agents (in addition to the security registrar) initially
designated by us with respect to any series of debt securities, we may at any
time rescind the designation of any such transfer agent or approve a change in
the location through which any such transfer agent acts, except that, if debt
securities of a series are issuable solely as registered securities, we will be
required to maintain a transfer agent in each place of payment for such series
and, if debt securities of a series are also issuable as bearer securities, we
will be required to maintain (in addition to the security registrar) a transfer
agent in a place of payment for such series located outside the United States.
We may at any time designate additional transfer agents with respect to any
series of debt securities. (Section 1002)

     In the event of any redemption in part, we shall not be required to

     - issue, register the transfer of or exchange debt securities of any series
       during a period beginning at the opening of business 15 days prior to the
       selection of debt securities of that series for redemption and ending on
       the close of business on (A) if debt securities of the series are
       issuable only as registered securities, the day of mailing of the
       relevant notice of redemption and (B) if debt securities of the series
       are issuable as bearer securities, the date of the first publication of
       the relevant notice of redemption, or if debt securities of the series
       are also issuable as Registered Securities and there is no publication,
       the mailing of the relevant notice of redemption, or

     - register the transfer of or exchange any registered security, or portion
       thereof, called for redemption, except the unredeemed portion of any
       registered security being redeemed in part, or

                                       10
   36

     - exchange any bearer security called for redemption, except that such a
       bearer security may be exchanged for a registered security of that series
       and like tenor, provided that such registered security shall be
       simultaneously surrendered for redemption. (Section 305)

  Payment and Paying Agents

     Unless we otherwise indicate in an applicable Prospectus Supplement,
payment of principal of and any premium and interest on bearer securities will
be payable, subject to any applicable laws and regulations, at the offices of
such paying agents outside the United States as we may designate from time to
time, in the manner indicated in such prospectus supplement. (Section 1002)
Unless we otherwise indicate in an applicable prospectus supplement, payment of
interest on bearer securities on any interest payment date will be made only
against surrender to the paying agent of the coupon relating to such interest
payment date. (Section 1001) No payment with respect to any bearer security will
be made at any of our offices or agencies in the United States or by check
mailed to any address in the United States or by transfer to any account
maintained with a bank located in the United States. Notwithstanding the
foregoing, payments of principal of and any premium and interest on bearer
securities denominated and payable in U.S. dollars will be made at the office of
our paying agent in New York City, if (but only if) payment of the full amount
thereof in U.S. dollars at all offices or agencies outside the United States is
illegal or effectively precluded by exchange controls or other similar
restrictions. (Section 1002)

     Unless we otherwise indicate in an applicable prospectus supplement,
payment of principal of and any premium and interest on registered securities
will be made at the office of such paying agent or paying agents as we may
designate from time to time, except that at our option payment of any interest
may be made by check mailed on or before the due date to the holder's registered
address or by wire transfer. (Section 307) Unless we otherwise indicate in an
applicable prospectus supplement, payment of any installment of interest on
registered securities will be made to the person in whose name such registered
security is registered at the close of business on the regular record date for
such interest. (Section 307)

     Unless we otherwise indicate in an applicable prospectus supplement, the
trustee will act as its own paying agent for payments with respect to debt
securities which are issuable solely as registered securities, and we will
maintain a paying agent outside the United States for payments with respect to
debt securities (subject to limitations described above in the case of bearer
securities) which are issuable solely as bearer securities or as both registered
securities and bearer securities. We will name any paying agents outside the
United States and any other paying agents in the United States initially
designated by us for the debt securities in an applicable prospectus supplement.
We may at any time designate additional paying agents or rescind the designation
of any paying agent or approve a change in the office through which any paying
agent acts, except that, if debt securities of a series are issuable solely as
registered securities, we will be required to maintain a paying agent in each
place of payment for such series and, if debt securities of a series are
issuable as bearer securities, we will be required to maintain (i) a paying
agent in New York City for principal payments with respect to any registered
securities of the series (and for payments with respect to bearer securities of
the series in the circumstances described above, but not otherwise), and (ii) a
paying agent in a place of payment located outside the United States where debt
securities of such series and any coupons appertaining thereto may be presented
and surrendered for payment. (Section 1002)

     All moneys paid by us to a paying agent for the payment of principal of and
any premium or interest on any debt security which remain unclaimed at the end
of one year after such principal, premium or interest shall have become due and
payable will (subject to applicable escheat laws) be repaid to us, and the
holder of such debt security or any coupon will thereafter look only to us for
payment thereof. (Section 1003)

  Global Debt Securities

     Debt securities of a series may be issued in whole or in part in the form
of one or more global debt securities that will be deposited with, or on behalf
of, a depository identified in the prospectus supplement relating to such
series. (Section 203) Unless and until it is exchanged in whole or in part for
the individual debt securities represented
                                       11
   37

thereby, a global debt security may not be transferred except as a whole by the
depository for such global debt security to a nominee of such depository or by a
nominee of such depository to such depository or another nominee of such
depository or by the depository or any nominee to a successor depository or any
nominee of such successor. (Section 305)

     We will describe the specific terms of the depository arrangement with
respect to a series of debt securities and certain limitations and restrictions
relating to a series of bearer securities in the form of one or more global debt
securities will be described in the prospectus supplement relating to such
series.

  Governing Law

     New York law will govern the indenture and the debt securities.

  Notices

     Except as otherwise provided in the indentures, notices to holders of
bearer securities will be given by publication at least twice in a daily
newspaper in New York City and in such other city or cities as may be specified
in such bearer securities. Notices to holders of registered securities will be
given by mail to the addresses of such holders as they appear in the security
register. (Section 106)

  Title

     Title to any bearer securities (including bearer securities in permanent
global form) and any coupons appertaining thereto will pass by delivery. We, the
Trustee and any agent of ours or the Trustee may treat the bearer of any bearer
security and the bearer of any coupon and the registered owner of any registered
security as the owner thereof (whether or not such debt security or coupon shall
be overdue and notwithstanding any notice to the contrary) for the purpose of
making payment and for all other purposes. (Section 308)

  Replacement of Securities and Coupons

     We will replace any mutilated debt security or a debt security with a
mutilated coupon appertaining thereto at the expense of the holder upon
surrender of such debt security to the trustee. We will replace debt securities
or coupons that became destroyed, stolen or lost at the expense of the holder
upon delivery to the trustee of the debt security and coupons or evidence of
destruction, loss or theft thereof satisfactory to us and the trustee; in the
case of any coupon which becomes destroyed, stolen or lost, we will replace such
coupon by issuance of a new debt security in exchange for the debt security to
which such coupon appertains. In the case of a destroyed, lost or stolen debt
security or coupon, an indemnity satisfactory to the trustee and us may be
required of the holder of such debt security or coupon before we will issue a
replacement debt security. (Section 306)

PROVISIONS APPLICABLE SOLELY TO SUBORDINATED DEBT SECURITIES

  Subordination

     Under the subordinated indenture, payment of the principal, interest and
any premium on the subordinated debt securities will be subordinated and junior
in right of payment to the prior payment in full of certain of our senior
indebtedness. (Section 1701) The indebtedness that will be senior indebtedness
with respect to a series of subordinated debt securities is described in the
subordinated indenture as may be modified by the applicable supplemental
indenture.

     The subordinated indenture provides that no payment of principal, interest
or premium may be made on the subordinated debt securities if:

     - we fail to pay the principal, interest, any premium or other amounts when
       due on any indebtedness described as specified senior indebtedness in the
       subordinated indenture as may be modified by the applicable supplemental
       indenture; or

     - we default in performing any other covenant in any senior indebtedness if
       the covenant default allows the holders of such specified senior
       indebtedness to accelerate the maturity of the specified senior
       indebtedness. (Section 1603)

     A covenant default will prevent us from paying the subordinated debt
securities only for up to 179 days after the holders of the specified senior
indebtedness notify us and the trustee that a blockage period has begun. The
holders of

                                       12
   38

specified senior indebtedness may only give one such notice during a 360 day
period. (Section 1603)

     The subordination does not affect our obligation, which is absolute and
unconditional, to pay, when due, principal of, premium, if any, and interest on
the subordinated debt securities. In addition, the subordination does not
prevent the occurrence of any default under the subordinated indenture. (Section
1606).

     The subordinated indenture will not limit the amount of senior debt that we
may incur. As a result of the subordination of the subordinated debt securities,
if we became insolvent, holders of subordinated debt securities may receive less
on a proportionate basis than other creditors.

  Conversion

     Under the subordinated indenture we may issue subordinated debt securities
which are convertible into or exchangeable for our common stock, preferred
stock, debt securities, other securities or property or securities or property
issued by another entity. Convertible subordinated debt securities will be
convertible on terms and at a conversion price described in the prospectus
supplement. (Section 301, 1501 and 1502) The subordinated indenture will provide
for adjustments in the conversion price if we make changes to our capital
structure. (Section 1504)

     If the securities are convertible into our common stock, the conversion
price will be subject to change if any of the following events occur:

     - we issue common stock as a dividend to our shareholders;

     - we subdivide, combine or reclassify our common stock;

     - we issue rights, which may be exercised for 45 days or less, to our
       shareholders to purchase common stock at a price per share less than the
       market price of the common stock at the time the rights are issued; or

     - we distribute to our shareholders debt securities, equity securities or
       assets, other than cash dividends paid from our surplus. (Section 1504)

     Adjustments in the conversion price may have tax consequences. These tax
consequences, if applicable, will be described in the prospectus supplement. We
also will not issue fractional shares upon conversion, but will pay the value of
a fractional share to the person who would otherwise be entitled to receive such
payment. (Section 1503)

     If we consolidate or merge with, or sell all or substantially all of our
assets to, another company, the convertible subordinated debt securities will be
convertible into the consideration that a holder of the convertible subordinated
debt securities would have received had the holder exercised the conversion
rights immediately before the consolidation, merger or sale. (Section 1505)

     If a series of subordinated debt securities is convertible into anything
other than our common stock, the prospectus supplement will describe the
following:

     - the events which will cause an adjustment in the conversion price;

     - any related tax consequences of the adjustments in the conversion price;

     - any special treatment of fractional shares; and

     - the effect of a consolidation, merger or sale of all or substantially all
       of our assets on the conversion rights.

                          DESCRIPTION OF CAPITAL STOCK

     Selected provisions of our organizational documents are summarized below.
The summary is not complete. You should read the organizational documents, which
are filed as exhibits to the registration statement, for other provisions that
may be important to you. In addition, you should be aware that the summary below
does not give full effect to the terms of the provisions of statutory or common
law which may affect your rights as a stockholder.

     We are authorized to issue 20 million shares of common stock and 2.5
million shares of

                                       13
   39

preferred stock. As of September 15, 1999, 8,557,906 shares of common stock were
outstanding and 1,045,461 shares of preferred stock were outstanding. As of
September 15, 1999, 255,492 shares of common stock were reserved for issuance
under our 1994 Stock Incentive Plan, 1996 Stock Incentive Plan and the 1997
Employee Stock Purchase Plan.

COMMON STOCK

  Listing

     Our common stock is listed on the New York Stock Exchange under the symbol
"CPE." Any additional common stock that we issue will also be listed on the New
York Stock Exchange, unless otherwise indicated in a prospectus supplement.

  Dividends

     Shareholders may receive dividends declared by our board of directors if,
as and when our board of directors declares any such dividends. The indentures
for our existing subordinated debt and our loan agreements with banks contain
restrictions on the payment of dividends.

  Fully Paid

     All of our outstanding shares of common stock are fully paid and
non-assessable. Any additional shares of common stock will also be fully paid
and non-assessable.

  Voting Rights

     Each share of common stock is entitled to one vote in the election of
directors and other matters submitted to our shareholders. Our common stock does
not have cumulative or preemptive rights.

  Other Provisions

     We will notify holders of common stock of any shareholders' meetings in
accordance with applicable law. If we liquidate, dissolve or wind-up, whether
voluntarily or not, our common stockholders will share equally in the assets
remaining after we pay our creditors and holders of our preferred stock.

  Transfer Agent and Registrar

     American Stock Transfer and Trust Company is the registrar and transfer
agent for our common stock.

PREFERRED STOCK

     The following description of the terms of the preferred stock sets forth
general terms and provisions of the preferred stock to which a prospectus
supplement may relate. Specific terms of any series of preferred stock offered
by a prospectus supplement will be described in the prospectus supplement
relating to such series. You should read the certificate of designations
establishing a particular series of preferred stock, which will be filed with
the SEC in connection with the offering of such series for other provisions that
may be important to you.

     Our board of directors can, without approval of our shareholders, issue one
or more series of preferred stock. The board can also determine the number of
shares of each series and the rights, preferences, privileges and restrictions
including the dividend rights, voting rights, conversion rights, redemption
rights and any liquidation preferences of any series of preferred stock and the
terms and conditions of issue. In some cases, the issuance of preferred stock
could delay a change in the persons and entities controlling us and make it
harder to remove present management. Under certain circumstances, preferred
stock could also restrict dividend payments to holders of our common stock or
restrict our ability to repurchase or redeem shares while there is an arrearage
in the payment of dividends to the holders of preferred stock.

     The preferred stock will, when issued, be fully paid and non-assessable.

     The transfer agent, registrar and dividend disbursement agent for a series
of preferred stock will be named in a prospectus supplement. The registrar for
preferred stock will send notices to shareholders of any meetings at which
holders of the preferred stock have the right to elect directors or to vote on
any other matter.

     If we offer preferred stock, the specific terms of a particular series will
be described in the prospectus supplement, and will include the following:

     - the maximum number of shares to constitute the series and the distinctive
       designations of such series;

       stock, and whether dividends will be cumulative;

     - whether and the manner in which the preferred stock will be redeemable;

     - any liquidation preference applicable to the preferred stock;

     - whether and the manner in which the preferred stock will be subject to a
       retirement or sinking fund that requires us to repurchase the shares;

     - any conversion rights applicable to the preferred stock;

     - any restrictions on the ability to sell or transfer the preferred stock;

     - any voting rights; and

     - any other preferences or other special rights or limitations.

  Series A Preferred Stock

     In November 1995, we issued and sold 1,315,500 shares of series A preferred
stock.

     Dividend Rights. Holders of the series A preferred stock are entitled to an
annual cash dividend of $2.125 per share, payable quarterly. If dividends are
not paid in full on all outstanding shares of the series A preferred stock and
any other security ranking on parity with the series A preferred stock,
dividends declared on the series A preferred stock and such other parity stock
are paid pro rata. Unless full cumulative dividends on all outstanding shares of
series A preferred stock have been paid, no dividends (other than in common
stock or other stock ranking junior to the series A preferred stock) may be
paid, or any other distributions made, on the common stock or on any other stock
of ours ranking junior to the series A preferred stock, nor may any common stock
or any other stock of ours ranking junior to or on a parity with the series A
preferred stock be redeemed, purchased or otherwise acquired for any
consideration by us (except by conversion into or exchange for stock of Callon
ranking junior to the series A preferred stock).

     Conversion. The series A preferred stock is convertible at any time prior
to being called for redemption into common stock at a rate of approximately
2.273 shares of common stock for each share of series A preferred stock, subject
to adjustment for certain antidilutive events. From time to time, we may reduce
the conversion price by any amount for a period of at least 20 days if the board
of directors determines that such reduction is in our best interests. In the
event of certain changes in control or fundamental changes, holders of series A
preferred stock have the right to convert all of their series A preferred stock
into common stock at a rate equal to the average of the last reported sales
prices of the common stock for the five business days ending on the last
business day preceding the date of the change in control or fundamental change.
We or our successor may elect to distribute cash to such holders in lieu of
common stock at an equal value.

     Exchange. The series A preferred stock may be exchanged at our option for
convertible debentures beginning on January 15, 1998 at the rate of $25
principal amount of convertible debentures for each share of preferred stock,
provided that all accrued and unpaid dividends have been paid and certain other
conditions are met. See "Convertible Debentures" below.

     Redemption. On or after December 31, 1998, we may from time to time redeem
the series A preferred stock at an initial redemption price of $26.488. On
December 31 of each year thereafter and until December 31, 2005, the redemption
price decreases. On December 31, 2005 and thereafter, the redemption price shall
remain at $25.

     Voting Rights. The holders of series A preferred stock have no voting
rights, except as otherwise provided by law. However, if dividend payments are
in arrears in an amount equal to or exceeding six quarterly dividends, the
number of our directors will be increased by two and the holders of the series A
preferred stock (voting separately as a class) will be entitled to elect the
additional two directors until all dividends have been paid. In addition, we may
not create, issue or increase the authorized number of shares of any class or
series of stock ranking senior to the series A preferred stock or alter, change
or repeal any of the powers, rights or preferences of the holders of the series
A preferred stock as to adversely affect such powers, rights or preferences.

     Convertible Debentures. At our option, the series A preferred stock may be
converted into convertible debentures. The convertible debentures, if issued,
will be issued under an indenture
                                       15
   41

between Callon and Bank One Columbus, NA, as
trustee, a copy of which is filed as an exhibit to our Form 10-K for fiscal year
1996. The convertible debentures will be our unsecured, subordinated
obligations, limited in aggregate principal amount to the aggregate liquidation
preference of the series A preferred stock and will mature on December 31, 2010.
We must pay interest on the convertible debentures semiannually following the
issue thereof at the rate of 8.5% per annum. The convertible debentures are to
be issued in fully registered form, without coupons, in denominations of $25 or
any integral multiple thereof.

     In a December 1998 private transaction, a preferred stockholder elected to
convert 59,689 shares of preferred stock into 136,867 shares of our common
stock. Subsequent to December 31, 1998, several other preferred stockholders,
through private transactions, converted 210,350 shares of preferred stock into
502,632 shares of our common stock under similar terms.

STAGGERED BOARD OF DIRECTORS

     Our certificate of incorporation and bylaws divide our board of directors
into three classes, as nearly equal in number as possible, serving staggered
three-year terms. The certificate of incorporation and bylaws also provide that
the classified board provision may not be amended without the affirmative vote
of the holders of 80% or more of the voting power of our capital stock. The
classification of the board of directors has the effect of requiring at least
two annual stockholder meetings, instead of one, to effect a change in control
of the board of directors, unless the articles of incorporation are amended.

DELAWARE ANTI-TAKEOVER STATUTE

     We are a Delaware corporation and are subject to Section 203 of the
Delaware General Corporation Law. In general, Section 203 prevents us from
engaging in a business combination with an "interested stockholder" (generally,
a person owning 15% or more of our outstanding voting stock) for three years
following the time that person becomes a 15% stockholder unless either:

     - before that person became a 15% stockholder, our board of directors
       approved the transaction in which the stockholder became a 15%
       stockholder or approved the business combination;

     - upon completion of the transaction that resulted in the stockholder's
       becoming a 15% stockholder, the stockholder owns at least 85% of our
       voting stock outstanding at the time the transaction began (excluding
       stock held by directors who are also officers and by employee stock plans
       that do not provide employees with the right to determine confidentially
       whether shares held subject to the plan will be tendered in a tender or
       exchange offer); or

     - after the transaction in which that person became a 15% stockholder, the
       business combination is approved by our board of directors and authorized
       at a stockholder meeting by at least two-thirds of the outstanding voting
       stock not owned by the 15% stockholder.

     Under the Section 203, these restrictions also do not apply to certain
business combinations proposed by a 15% stockholder following the disclosure of
an extraordinary transaction with a person who was not a 15% stockholder during
the previous three years or who became a 15% stockholder with the approval of a
majority of our directors. This exception applies only if the extraordinary
transaction is approved or not opposed by a majority of our directors who were
directors before any person became a 15% stockholder in the previous three
years, of the successors of these directors.

LIMITATION ON DIRECTORS' LIABILITY

     Delaware has adopted a law that allows corporations to limit or eliminate
the personal liability of directors to corporations and their stockholders for
monetary damages for breach of directors' fiduciary duty of care. The duty of
care requires that, when acting on behalf of the corporation, directors must
exercise an informed business judgment based on all material information
reasonably available to them. Absent the limitations allowed by the law,
directors are accountable to corporations and their stockholders for monetary
damages for acts of gross negligence. Although the Delaware law does not change
directors' duty of care, it allows corporations to limit available relief to
equitable remedies such as

                                       16
   42

injunction or rescission. Our certificate of incorporation limits the liability
of our directors to the fullest extent permitted by this law. Specifically, our
directors will not be personally liable for monetary damages for any breach of
their fiduciary duty as a director, except for liability

     - for any breach of their duty of loyalty to the company or our
       stockholders;

     - for acts or omissions not in good faith or that involve intentional
       misconduct or a knowing violation of law;

     - under provisions relating to unlawful payments of dividends or unlawful
       stock repurchases or redemptions; or

     - for any transaction from which the director derived an improper personal
       benefit.

     This limitation may have the effect of reducing the likelihood of
derivative litigation against directors, and may discourage or deter
stockholders or management from bringing a lawsuit against directors for breach
of their duty of care, even though such an action, if successful, might
otherwise have benefitted our stockholders.

                       DESCRIPTION OF SECURITIES WARRANTS

     We may issue securities warrants entitling the holder to purchase our debt
securities, preferred stock or common stock as described in the prospectus
supplement relating to the issuance of the securities warrants. Securities
warrants may be issued independently or together with other of our securities
and may be attached to or separate from other securities. The securities
warrants will be issued under warrant agreements to be entered into between us
and a bank or trust company that acts as warrant agent. The warrant agent will
act solely as our agent in connection with securities warrants and will not
assume any obligation or relationship of agency or trust for or with any holders
of securities warrants or beneficial owners of securities warrants.

     The specific terms of any securities warrants will be described in the
applicable prospectus supplement.

INTRODUCTION

     The prospectus supplement will describe the terms of any securities
warrants offered, including the following:

     - the amount of securities warrants to be registered and the purchase price
       and manner of payment to acquire the securities warrants;

     - a description, including amount, of the debt securities, preferred stock
       or common stock which may be purchased upon exercise;

     - the exercise price which must be paid to purchase the securities upon
       exercise of a securities warrant and any provisions for changes or
       adjustments in the exercise price;

     - any date on which the securities warrants and the related debt
       securities, preferred stock or common stock will be separately
       transferable;

     - the dates on which the right to exercise the securities warrants shall
       commence and expire;

     - a discussion of certain U.S. federal income tax, accounting and other
       special considerations, procedures and limitations relating to the
       securities warrants; and

     - any other material terms of the securities warrants.

     Holders of securities warrants will not have any of the rights of holders
of our debt securities, preferred stock or common stock that may be purchased
upon exercise until they exercise the securities warrants and receive the
underlying securities. These rights include the right to receive payments of
principal of, any premium on, or any interest on, the debt securities
purchasable upon such exercise or to enforce the covenants in the indentures or
to receive payments of dividends on the preferred stock or common stock which
may be purchased upon exercise or to exercise any voting right.

EXERCISE OF SECURITIES WARRANTS

     After the close of business on the expiration date described in the
prospectus supplement, securities warrants will expire and the holders will
                                       17
   43

no longer have the right to exercise the securities warrants and receive the
underlying securities. Securities warrants may be exercised by delivering a
properly completed certificate in the form attached to the securities warrants
and payment of the exercise price as provided in the prospectus supplement. We
will issue and deliver our debt securities, preferred stock or common stock as
soon as possible following receipt of the certificate and payment described
above. If less than all of the securities warrants represented by a certificate
are exercised, we will issue a new certificate for the remaining securities
warrants. The foregoing terms of exercise may be modified by us in a prospectus
supplement.

                  DESCRIPTION OF SECURITIES PURCHASE CONTRACTS
              AND SECURITIES PURCHASE UNITS AND PREPAID SECURITIES

     We may also issue securities purchase contracts which obligate the holder
of the contracts to purchase, and obligate us to sell, our common stock or
preferred stock at one or more times in the future. The prospectus supplement
will describe the terms of any securities purchase contracts, including the
following to the extent applicable:

     - whether the holder is obligated to purchase our common stock or preferred
       stock, and the dates on which such shares must be purchased;

     - the purchase price of the common stock or preferred stock, which may be
       fixed at the time of issuance or determined in the future by a formula;

     - any periodic payments that we must make to the holders of the securities
       purchase contracts, or any periodic payments that the holders must make
       to us and whether these periodic payments are unsecured or prefunded in
       some manner; and

     - any collateral that a holder of securities purchase contracts is
       obligated to pledge to secure the holder's obligations to purchase
       securities and make periodic payments under the contract.

     Securities purchase contacts may be issued with our debt securities,
preferred stock or other securities as a unit, referred to as a "securities
purchase unit." If securities purchase units are issued, the debt securities,
preferred stock or other securities which are part of the units may be pledged
to secure the holder's obligation to purchase the common stock or preferred
stock and to make any periodic payments provided for in the securities purchase
contract. A securities purchase unit may also provide for the substitution of
U.S. Treasury securities or securities of other persons for the debt securities,
preferred stock or other securities initially issued as part of the securities
purchase units. Securities purchase units may also give a financial institution
or other person the right to purchase the debt securities, preferred stock or
other securities which are part of the securities purchase units. We may also
have the right or obligation to deliver newly issued prepaid securities purchase
contracts ("prepaid securities") upon release to a holder of any collateral
securing the holder's obligations under the original stock purchase contract.
Any such purchase rights will be described in a prospectus supplement.

                              PLAN OF DISTRIBUTION

     We may sell the securities

          (1) through underwriters or dealers;

          (2) through agents;

          (3) directly to purchasers;

          (4) through remarketing firms; or

          (5) through a combination of any such methods of sale.

     Any such underwriter, dealer or agent may be deemed to be an underwriter
within the meaning of the Securities Act of 1933.

                                       18
   44

UNDERWRITERS OR DEALERS

     If underwriters are utilized in the sale, the securities will be acquired
by the underwriters for their own account. The underwriters may sell the
securities in one or more transactions, including negotiated transactions, at a
fixed public offering price or at varying prices determined at the time of sale.
The obligations of the underwriters to purchase the securities will be subject
to several conditions set forth in an agreement between us and the underwriters.
The underwriters will be obligated to purchase all of the securities offered if
any of the securities are purchased. Any public offering price and any discounts
or concessions allowed or re-allowed or paid to dealers may be changed from time
to time. We may grant underwriters who participate in the distribution of
securities an option to purchase additional securities if they sell more
securities than they purchased.

     During and after an offering through underwriters, the underwriters may
purchase and sell the securities in the open market. These transactions may
include overallotment and stabilizing transactions and purchases to cover
syndicate short positions created in connection with the offering. The
underwriters may also impose a penalty bid, in which selling concessions allowed
to syndicate members or other broker-dealers for the offered securities sold for
their account may be reclaimed by the syndicate if such offered securities are
repurchased by the syndicate in stabilizing or covering transactions. These
activities may stabilize, maintain or otherwise affect the market price of the
offered securities, which may be higher than the price that might otherwise
prevail in the open market. If commenced, these activities may be discontinued.

     If we use dealers in the sale of securities, we will sell the securities to
them as principals. They may then resell those securities to the public at
varying prices determined by the dealers at the time of resale. We will include
in the prospectus supplement the names of the dealers and the terms of the
transaction.

AGENTS

     We may designate agents who agree to use their reasonable efforts to
solicit purchasers for the period of their appointment or to sell securities on
a continuing basis.

DIRECT SALES

     We may also sell securities directly to one or more purchasers without
using underwriters or agents.

REMARKETING FIRMS

     The securities may be re-sold to the public following their redemption or
repayment by one or more remarketing firms. Remarketing firms may act as
principals for their own accounts or as agents for us.

RIGHTS OFFERINGS; CONVERSIONS

     If we were to issue rights on a pro rata basis to our shareholders, we may
be able to use this prospectus to offer and sell the securities underlying the
rights. We may also be able to use the prospectus to offer and sell securities
to be received upon conversion of any convertible securities we may issue or
upon exercise of transferable warrants that may be issued by us or an affiliate.

GENERAL INFORMATION

     Underwriters, dealers, agents and remarketing firms that participate in the
distribution of the securities may be underwriters as defined in the Securities
Act of 1933, and any discounts or commissions received by them from us and any
profit on the resale of the securities by them may be treated as underwriting
discounts and commissions under the Securities Act of 1933. Any underwriter,
dealer, agent or remarketing firm will be identified and the terms of the
transaction, including their compensation, will be described in a prospectus
supplement. We may have agreements with underwriters, dealers, agents or
remarketing firms to indemnify them against certain liabilities, including
liabilities under the Securities Act of 1933, or to contribute with respect to
payments which the underwriters, dealers or agents may be required to make.
Underwriters, dealers, agents or remarketing firms, or their affiliates may be
customers of, engage in transactions with or perform services for, us or our
subsidiaries in the ordinary course of their business.

     All debt securities will be new issues of securities with no established
trading market. Any underwriters to whom debt securities are sold by
                                       19
   45

us for public offering and sale may make a market in such securities, but such
underwriters will not be obligated to do so and may discontinue any market
making at any time without notice. No assurance can be given as to the liquidity
of the trading market for any debt securities.

     We may use agents and underwriters to solicit offers by certain
institutions to purchase debt securities from us at the public offering price
set forth in the prospectus supplement pursuant to delayed delivery contracts
providing for payment and delivery on the date stated in the prospectus
supplement. Delayed delivery contracts will be subject to only those conditions
set forth in the prospectus supplement. A commission indicated in the prospectus
supplement will be paid to underwriters and agents soliciting purchases of debt
securities pursuant to delayed delivery contracts accepted by us.

for any agents, dealers or underwriters.
